I took a chance on a cheaper walnut stock than the TX ….and I used an aerosol can of degreaser
The type used on oil on engine parts ..the sort that puts a foam where you spray.
Well how do you find out if you don't try it ??? we wouldn't be where we are today if folk didn't "try something"
Anyhow ...foam on.....agitate / rubbed it in ...wiped it off like you would an oily engine part …
let it dry ...

Came up a treat
No trace of any wax or oil ….basically as a virgin piece of walnut again.

Re oiled it to my taste.
